Gambogic acid is a naturally occurring xanthonoid extracted from the resin of trees belonging to the Garcinia genus—most notably, Garcinia hanburyi. This tree is native to regions in Southeast Asia, particularly found in areas of China, India, and neighboring countries.
Gambogic acid (GA; C38H44O8, MW: 628.76), a polyprenylated xanthone and a widely used coloring agent, is the main active ingredient of gamboges secreted from the Garcinia hanburyi tree ([3, 4], which mainly grows in Southeast Asia.
GA has been approved by the Chinese FDA for the treatment of solid cancers in Phase II clinical trials.
Pathways:
-evidence suggesting that it can inhibit thioredoxin reductase (TrxR).
-can indeed lead to an increase in reactive oxygen species (ROS) levels
-Gambogic acid can trigger mitochondrial dysfunction, leading to cytochrome c release
-influences death receptors
-Inhibition of NF-κB Signaling
-Inhibition of VEGF Pathway
